Conclusion

As you can see the alleged marriage of Umme Kalthum to Umar is a lie, which is so full of holes and contradictions that it throws up more questions than proofs. The Nasibi assumed that our failure to reply was be cause we had none, but in fact we remained silent so as not to expose and humiliate them. Sadly they deemed our sincerity to be weakness and exploited this to the maximum.

The reality is that Sayyida Umme Kalthum (as) married on only one occasion and that was to Aun bin Ja'far. The Umme Kalthum that married Umar ibn al Khattab in 17 Hijri was someone else. The wife of Umar died during the reign of Mu'awiya bin Hind, whilst Umme Kalthum the daughter of Sayyida Fatima (as) was witness to the tragedy of Kerbala and died after 62 Hijri.

Textual evidence from Sunni and Shi'a sources and common sense therefore dictates that Umme Kalthum the daughter of Maula 'Ali (as) and Sayyida Fatima (as) never married Umar ibn al Khattab, this entire claim is false. If the Ahl'ul Sunnah wish to blindly cling to this concept as part of their aqeedah, then we should stress to do so means destroying the reputation of Umar, and is also very disrespectful to Hadhrath 'Ali (as).
